PUMP.

SPECIFICATION forming part of Letters Patent No. 255,966, dated April 4,1882,

Application filed November 19, 1881.

To all whom it may concern.-

Beitknown thatI, MOSES G-AYMAN, ot Canal Winchester, in the county ofFranklin and State of Ohio, have invented a new and useful Improvementin Pumps, ot which the following is a i'ull, clear, `and exactdescription.

Reference is to be had to the accompanying drawings, forminga part ot'this specification, in which similar letters ot' reference indicatecorresponding parts in all the figures.

Figure 1 is a sectional elevation of my improved pump. Fig. 2 is a sideelevation of the plunger or bucket, and Fig. 3 is a plan view ofthesame.

The invention consists in certain combinations which will be describedin connection with the drawings, and then pointed out in the claims.

This pump is adapted to be used in either open wells, driven wells, orcisterns, or at any place where a pump is wanted, and to be used forextinguishing tires, sprinkling streets, 85e., and it is not to be hungupon the curb or platform of the well, as is the case with ordinaryforce and lift pumps, but is adapted to be snpported at or from thebottom ot' the well.

The water-chamber A may be made of iron or of wood. Ifmade of wood, theside openings, d d', will be faced with the iianged andinternally-threaded metal thimbles c o', and the central opening,f, willbe faced with the eX- ternally-threaded annular metal cup or collar g,which is provided with the annular screwcap h, which, together with thecup g, forms the stuffing-box e, which surrounds and makes a tight jointwith the valve-rod D, or with the sleeve E, as the case may be.

In the thimble a is screwed the air-chamber B, and in the thimble a isscrewed the discharge-tube F. In case the chamberA is made of iron, ofcourse the side openings will be in. tcrnallythreaded to receive andhold the airchamber and the eduction or discharge pipe, and the thimblesa and a will be dispensed with.

In the opening j in the under side of the chamber A, which registerswith the opening j', is secured, preferably by means of the braces (Nomodel.)

c c, the large induction-pipe L, in which the valve or bucket J, securedupon the lower end ofthe rod D, moves. To the lower end ofthe pipe orcylinder L is secured the bottom pipe, G, which may be wood or iron.When it is wood it carries at its upper end the tlapvalve K, and when itis iron the ap-valveis secured in the bottom ot' the cylinder L. Thelower end ot' the pipcG rests on the bottom of the well at i t' and'supports the whole pump. The valve or bucket J has secured upon itsupper end the leather sleeve a, which projects above the solid portionofthe valve or bucket, as shown in Fig. 1.

VVthin the space surrounded by the leather sleeve, above the solidportion of the valve or bucket, is placed upon the rod D the circularleather flap or disk p, which is held upon the upper end ofthe solidportion of the bucket by the nut s, and serves to close in the ordinaryway the passages t t through the solid portion of the bucket. By thismeans the flap is protected from contact with the walls of the pipe L,and the edge ot' it coming against the inner wall of the leather sleevewhen closed makes a tightjoint therewith and prevents all backward ow ofwater.

In case the pump is to be made double-acting, I place upon the rod D theinverted elongated cup or sleeve E, which moves with the said rod andserves to diminish the space in the water-chamber and cylinder upon thedownstroke of the rod, and thus forces the water therefrom through thedischarge or eduction pipe. This inverted cup or sleeve is adjustablevertically upon the rod by means of the screw-thread of the rod,as willbe clearly understood from the drawings.

The spout H is made reversible, or so that it can be turned to eitherside ot' the pipe F to suit the position of the pump-handle I. This isaccomplished by means ot' the threeway joint K, which is internallyscrewthreaded at all ofits openings, as shown, and receives the upperendof the pipe F, 'the horizontal spout H, and the fulcrum-post N ofthelever. Thisjoint may be turned so as to hold the spout in any directionfrom the pipe F desired.

The pipe F is provided with the perforation or winter-leak 7c. Below theperforation or leak is riveted the spring l, which closes over theperforation while water is being forced through the pipe F, but whichautomatically springs back to the position shown in the dra-wings whenpumping ceases, and thus opens the leak and permits the water in thepipe to escape.

In case the pump is not to be made doubleacting, the inverted cup orsleeve E will not be used, and, as above intimated,the stufling-box ewill be made to tit the rod D, or the rod may be made to tit so closelyin the openingf that a stufng-box will not be needed.

The induction-pipe L, instead ot' being held by the rods or braces c c,may be screwed into the water-chamber.

The water chamber A and induction pipe or cylinder L may be made as onecasting or frame,

with an opening or passage upward through the water-cham bersufficiently large to admit the valve or bucket J, and thispassage tohave openings at eilhrr side to admit the water to the openings d df,and the top of this passage to be closed by means ofa metal plate havingin it the stuffing-box e.

I am aware that it is not new to use an airchamber screwed in the upperend of stock or cannected rigidly with the plunger, or to make vanair-chamber in the form of an inverted cup on the end of piston-rod; but

What I claim as new is- 1. The combination, with the externallyendthreaded pipes F Hand fulcrum-post N,of the three-way joint K,internally screw-threaded at each of its openings, as and for thepurpose specified.

2. The combination, with the dischargepipe F, having waste-hole 7e', ofthe platespring fastened at bottom, arranged to cover thehole when thepump is in operation and to spring away from the hole as soon as thepumpceases to work, as shown and described.
